How can you tell if you have Adaptive lights?
I ordered my vehicle with Adaptive lights and went in an underground car park today. When I had them on an Audi a few years ago, you could really see the lights move left-right with the direction of the steering wheel. I didn't see anything of the sort on the Disco today.
The Audi's worked on dipped as well as full/main beam.
Please advise.

The D3 units used to move when you turned the wheel while stationery ...the D4 ones appear to be far more controlled in relation to speed and steering angle
EDIT here's some more info
Quote:
AFS Control Module
The AFS control module is connected to the high speed CAN bus and receives inputs from other vehicle systems on the status of the following parameters:
Steering angle - from steering angle sensor
Vehicle speed - from ABS module
Low beam status - from IC
Suspension height - from air suspension control module
Odometer value - for diagnostics only
Engine running - from ECM
Gear position - From transmission control module or transfer box control module
Engine crank - from ECM
Exterior/interior temperature - for diagnostics only.
The AFS will only operate when the AFS control module receives an engine running signal on the CAN bus. When the engine running signal is received, the AFS control module performs an initialization routine which is only performed at engine crank (power mode 9).
The AFS will also function when the lighting control switch is in the AUTO position and the AFS control module receives a lights on signal from the rain/light sensor and an engine running signal.
The AFS control module then monitors the inputs from the other vehicle systems to control the AFS functionality according to cornering angles and vehicle speed.
The AFS control module is connected to each headlamp on a private Local Interconnect Network (LIN) bus. The AFS control module then drives the DC motor actuators inside the headlamp assembly.
The AFS control module controls the swiveling angle of each projector module using speed and steering angle signals. The angles of each projector module differ to give the correct spread of light, For example, when turning left, the left projector module will have a greater swiveling angle than the right projector module
Reverse mode disables the swivel function when reverse gear is selected. The AFS projector modules move to their central straight ahead position and the static bending lamp, if active, will go off. When reverse gear is deselected, the AFS projector modules will move to a position to match the steering angle and the static bending lamp will illuminate if the operating conditions are correct (for example vehicle speed above 1.86 mph (3 km/h).
Quote:
The static bending lamps operate with a steering angle sensor signal which is received by the AFS control module. The AFS control module sends a static bending lamp on request to the CJB which activates the static bending lamp bulb.
The static bending lamp operation is variable with the speed of the vehicle and the steering wheel angle. The static bending lamps illuminate at 0 mph (0 km/h) when the steering wheel rotation reaches 20 degrees. At 43 mph (70 km/h) the static bending lamps will illuminate when the steering wheel angle reaches 10 degrees. The static bending lamps will be switched off when the vehicle speed exceeds 43 mph (70 km/h).
The operation of the static bending lamps is controlled by the AFS control module. When the operation parameters of the lamp are reached, the CJB fades the static bending lamp bulb on using a PWM voltage over a period of approximately 2 seconds. When the lamp is switched off, the CJB fades the bulb off by decreasing the PWM voltage.

I have them on mine and can't really see them moving very much when manoeuvring in a car park, if you drive up to a wall or a fence in the dark and move your steering you should see a bit of movement Cheers Ian

Start the car up against a wall at night and turn on the lights, if they are adaptive you will see them move slightly, I thought the same with mine but you can see the movment b the above method.MY17 D5 1st Edition Namib Orange

I'm confused.
The overly technical explanation of the AFS function is not what I was after.
I was basically asking for a simple explanation and what to look for given I could see NO visible changes to the beam when cornering in an underground carpark where the auto dipped lights had activated.
Please advise.

Sorry to disappoint I shan't bother wasting my time trying to be helpful in future
Can I advise a more simple application of using your eyes 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021

Sorry if I have offended. The explanation of how the system works is great, but I was really looking for information about how to actually tell if the system is working / present in a simple, easy way.
No real vehicle handover on a technical level, so....
